I would like to ask this question to an audience during a presentation and follow with an explanation. I wonder which form is correct—Why we are here? or Why are we here?
I understand that the correct form should be Why are we here?, but the form Why we are here in the context of religion, for example, is quite popular.
Is Why we are here? a grammatical mistake? If so, then what is the correct context in which to use Why we are here?
I tried to search Google, but the sentence is too general and it is hard to find anything.
